I’m excited to share a tool I’ve been building: a stock screener + portfolio optimizer. It helps you:
Pinpoint stocks that fit your risk profile (two quick questions)
Inspect key fundamentals (EPS, revenue segmentation, insider trades, financial ratios, price targets)
Optimize portfolio weights to minimize risk for a target return using the Markowitz model
